  • Patent number: 12385480
    Abstract: Devices and methods for operating a diaphragm compressor. Embodiments of the present disclosure comprise an oil piston being driven to pressurize work oil against the diaphragm of the compressor. In embodiments, an injection pump provides a supplemental flow of work oil in the region of pressurized fluid, and such pump may be part of an actively controlled system. In embodiments, a pressure relief valve vents an overpump flow of work oil, and such valve may be variable. Embodiments provide feedback and control mechanisms, including control of the injection pump and the relief valve.

  • Publication number: 20250087711
    Abstract: Electrochemical cell systems (51) and electrochemical cell processes are described as applicable to power generation or electrolysis modes with systems that have a containment vessel interior space multiple electrochemical cell stack, stack inlet plenum (43) that can accommodate thermal expansion and contraction in an economical way and that can provide a substantially equivalent environment for each stack inlet as well as can include, if desired, either or all of a vessel external compression stack mount possibly configured as a cathode outlet manifold (111) configured as a stack mount, a fully accommodative thermal expansion-contraction electrochemical cell stack mount possibly configured with external springs (91), and even the possibility of an axial flow adjuster such as a gradation plate (99) for better operation.
